The looks don't change much but the power difference is incredible! Its like nearly 4 times his regular power at full power. Super saiyan is like only 2 times his full power at normal.
he turned into super saiyan 2 when he turned into Majin vegeta by Babidi
Gogeta, the fusion of super saiyan 4 Goku and Vegeta.
*sigh* No there is not a password for super saiyan vegeta in tenkaichi however, there is a password for super saiyan 4 vegeta in dragonball z tenkaichi 2.
Vegeta was super saiyan 2 against kid Buu.
yes there is. He became super saiyan 2 when he became majin vegeta by Babidi and since then he was able to transform at will.
Gohan can't go Super Saiyan 4- only pure Super-Saiyans (Like Vegeta) can do that, and Gohan is half-human.
Vegeta is stronger than piccolo because vegeta can become a super saiyan and vegeta is also from the saiyan race which greatly improves his will to fight
Yes, Vegeta reached Super Saiyan in the beginning of the Cell Saga. He stated that he had "reached his limits, and in his rage became a super saiyan."
there is no such thing as super saiyan 5
